DESCRIPTION OF THE EMBODIMENTS
FIG. 1 is a partial cross-sectional schematic view of a display module according to an embodiment of the present invention. FIG. 2 is a schematic view of an assembling element of the display module in FIG. 1. FIG. 3 is a partial schematic view of the display module in FIG. 1 illustrating the display panel is positioned to the protective plate through the assembling elements. Referring to FIG. 1 to FIG. 3, the display module 100 of the present embodiment includes a display panel 110, at least one bracket 120, a protective plate 130, a plurality of assembling elements 140 and a back cover 150.
In the embodiment, the display panel 110 is, for example, a TFT-LCD (thin film transistor liquid crystal display) panel and can be a touch display panel, and the present invention is not limited thereto. The display panel 100 has a display surface 112 and a back surface 114 opposite to the display surface 112. The bracket 120 is fixed to the display panel 110. The at least one bracket 120 in this embodiment includes two brackets as shown in FIG. 2, and the two brackets 120 are fixed to the two opposite edges of the display panel 110 respectively by means of screwing or by other suitable assembling manner.
In addition, the protective plate 130 can be formed by glass, plastic or other transparent material. The peripheral of the protective plate 130 may be decorated with black ink for a purpose of obscuring or hiding the assembling elements. The protective plate 130 faces the display surface 112. The assembling elements 140 are fixed on the protective plate 130, wherein each of the assembling elements 140 has a positioning protrusion 142 and an engaging slot 144. And the bracket 120 is positioned on the assembling elements 140 through the positioning protrusions 142. The back cover 150 is to cover and protect the display panel 110 and also can be an ornamental cover of the display module 100. The back cover 150 faces the back surface 114, wherein the back cover 150 is engaged to the assembling elements 140 through the engaging slots 144.
More specifically, the assembling elements 140 are disposed on the edges of the protective plate 130 with the location of the assembling elements 140 corresponding to the brackets 120 in this embodiment. In other embodiments, the assembling elements 140 can be disposed at all the edges of the protective plate 130 and the present invention is not limited thereto.
FIG. 4 is an enlarged view of a portion of FIG. 3. Referring to FIG. 1, FIG. 2 and FIG. 4 together, in order to position the brackets 120 fixed with the display panel 110 to the protective plate 130, each of the brackets 120 has a plurality of positioning holes 122, and the positioning protrusions 142 of the assembling elements 140 are respectively inserted into the positioning holes 122. In this way, the brackets 120 are positioned by inserting the positioning protrusions 142 into the positioning holes 122.
In addition, the back cover 150 has a plurality of hooks 152 disposed in the inner sidewalls near the edges of the back cover 150 (only one hook 152 is shown in FIG. 1). The hooks 152 are respectively engaged to the engaging slots 144 so that the back cover 150 can be engaged to the assembling elements 140. FIG. 5 shows before the back cover of the display module in FIG. 1 is engaged to the assembling element. Referring to FIG. 1 and FIG. 5 together, when the back cover 150 is engaged to the assembling elements 140, each of the hooks 152 is adapted to slide into the corresponding engaging slot along a direction D1 parallel to the back surface 114. In such configuration, the back cover 150 is fixed to both of the display panel 110 and the protective plate 130 only by means of their structural restrictions.
Then, the configuration of the assembling elements 140 are described as follows. FIG. 6 is the assembling element of FIG. 2 viewing from the bottom side. Referring to FIG. 1, FIG. 2 and FIG. 6 together, each of the assembling elements 140 has an attaching surface 146. In this embodiment, the assembling element 140 is fixed to the protective plate 130 through an adhesive 50 adhered between the attaching surface 146 and the protective plate 130. The adhesive 50 can be a double-sided foam tape, super glue or the like.
In order to prevent the adhesive overflow and affect the appearance of the display module, the assembling element 140 further has a wall W disposed on the attaching surface 146 and surrounding the adhesive 50. In addition, the assembling element 140 can also has an overflow groove G disposed on the attaching surface 146 and receiving the adhesive 50, specially the overflowed adhesive.
In general, air bubbles may be generated when the adhesive 50 is attached to objects, and thus in the embodiment, a plurality of air vents 148 can be disposed on the attaching surface 146 so as to exhaust the generated air bubbles. As shown in FIG. 6, the air vents 148 extend from the attaching surface 146 to an inner surface 144 a of the engaging slot 144. The air vents 148 are covered by the adhesive 50 (only shown in FIG. 1 and FIG. 5) at the attaching surface 146 after the adhesive 50 is adhered. In this way, each of the assembling elements 140 is properly stuck on the edges of the protective plate 130.
In this embodiment, additional assembling elements 140 can also be disposed on the edges of the protective plate 130 on which the brackets 120 are not fixed as shown in FIG. 1. In this condition, the back cover 150 can be fixed to the protective plate 130 by respectively engaging the hooks 152 to the engaging slots 144 of the assembling elements 140 disposed on all of the edges of the protective plate 130 to achieve a better fixing effect.
After the display panel 110 fixed to the brackets 120 is positioned to the assembling elements 140 by respectively inserting the positioning protrusions 142 into the positioning holes 122, the display panel 110 can be firmly fixed to the assembling elements 140 by means of screwing. Therefore, a fastening hole H1 can be disposed on each of the assembling elements 140 and a plurality of fastening holes H2 can be correspondingly disposed at the brackets 120, so that the brackets 120 are screwed on the assembling elements 140 through the fastening holes H1 and H2. However, it has to be noted that the way of fastening the brackets 120 to the assembling elements 140 is not limited in the present.
In light of the foregoing, the display module of the present invention includes assembling elements fixed to the protective plate. The display panel and the bracket are positioned to the assembling elements through the positioning protrusions disposed thereon, and the back cover is engaged to the assembling elements through the engaging slots disposed thereon. The protective plate is not stuck to the display panel, since no glue is used in the assembling and the positioning protrusions of the assembling elements are used instead. Accordingly, the display module is capable to easily disassemble the components of the display module for repair, and the shortcomings of the conventional display module that assembling tolerances and gap differences may formed between the components of the display module during disassembling for repair can further be prevented. Furthermore, the assembling elements of the present invention are simple in structure and the manufacturing cost can also be reduced.
It will be apparent to those skilled in the art that various modifications and variations can be made to the structure of the present invention without departing from the scope or spirit of the invention. In view of the foregoing, it is intended that the present invention cover modifications and variations of this invention provided they fall within the scope of the following claims and their equivalents.
